Do the complex numbers for a group under binary operation ' plus '?
Yes, the complex numbers, as well as the real numbers which are a subset of the complex numbers, form groups under addition.
How can you order decimals fractions and mixed numbers on a number line?
The easiest way is to convert the mixed numbers and fractions to decimals by dividing the numerators (top) numbers by the denominator (bottom) numbers of each fraction - for a mixed number, the whole number needs to be added on.Then, comparing the whole numbers order as much as possible the numbers. Start with the tenths digit (the digit immediately to the right of the decimal point)Sort those groups of numbers with the same digits so far based on the current decimal digitIf there are still groups of numbers, use the next decimal digit (hundredth, thousandth, etc) until a distinction can be made.Where there are a group of numbers with the same whole number, start looking at the decimal digits:Write the list out of numbers out in their original form (decimal, fraction or mixed number).
Can unequal groups only be added in math?
No, any operation can be done to them.
How many groups of 3 are there in one group of 6 numbers?

How do you lay the blocks out for decimal numbers?
